s'claims. (cm2- 142) My invention relates to shoe manufacture, andparticularly to the making of shoes having soles adhesively secured tothe shoe bottoms.

It is an objectl of my invention to make a shoe without an insole byemploying a turn shank with a sock lining. Thus it is my object to makea shoe having a single sole only just as a turn shoe, thereby achieving,without the expensive turning operation, a shoe with increased soleflexibility `and having greater comfort than a turn shoe.

It is an object of my invention to make a shoe which does not requirechannels or stitches in the sole, so that the inside is much smootherand more comfortable than shoes heretofore made.

Another object of my invention is the avoidance of the necessity ofapplying the sock lining after the shoe is made up, and in which thecost of the insole is eliminated.

The above objects and other objects to which reference will be made inthe ensuing disclosure, I accomplish by that certain combination andarrangement of parts of which I have illustrated a preferred embodiment.

Referring to the drawing:-

Figure 1 is a side perspective view of a last showing the first step inmy new shoe manufacture.

Fig. 2 is a bottom view of the last showing subsequent steps in myprocess.

Fig. 4 is a side elevation of a finished shoe.

Fig. 5 is a sectional view taken along the lines 5-5 in Fig. 4.

The first operation is to secure the sock lining 1 with its innersurface against the bottom surface of the last 2. Preferably thesocklining is secured on the last with a weak cement, which will allow readydetachment and then can be readily 40 removed with a solvent so that theinside of the shoe will be clean and unstained.

The next step is the application of a turn shank 3, which may be securedin position as indicated lin Fig. l, with several tacks 4. p

The upper 5 is then stretched over the last and tacked to the last aswith tacks 6. Previously cement 7 is applied to the exposed surface ofthe sock lining and turn shank, and after a short interval the upperwill adhere tightly to the sock liner and shank.

The tacks 6 are then withdrawn and the shoe bottom is then skived osmooth, las indicated at 8 in Fig. 2. Cement is then applied to the shoebottom, and the outsole 9 is then cemented in position.

The shoe is then put in a press to cause a rm bond between the sole andshoe. bottom. After removal from the press, the shoe is withdrawn fromthe last and the heel 10 is applied, and the other usual steps offinishing accomplished.

It will thus be observed that while employing some well known steps inshoe manufacture, I achieve a turn shoe effect without the expensivesteps used in turn shoe manufacture.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, iszshank, then skiving said edge portions, andthen i adhesively securing a sole to said edge portions and the shank.

2. The method of manufacturing a shoe wherein a sock lining forms theinsole, which comprises securing the sock lining to the bottom of thelast by a readily dtachable and removable adhesive, then temporarilysecuring a shank piece to the last over the sock lining, then applyingan upper to the last and adhesively securing its edge portions to thesock lining and the shank, then skiving said edge portions, and thenadhesively securing a sole to said edge portions and the shank.

- 3. The method of manufacturing a shoe wherein a sock lining forms theinsole, which comprises securing a sock lining to the bottom of a lastby temporary means, then securing a turn shank' to the last over` thesock, lining by temporary means, then applying an upper to the last andadhesively securing its edge portions to the sock lining and shank, thenskiving said edge portions, and then adhesively securing a sole to saidedge portions of the upper and-to the shank.

4. The method of manufacturing a shoe wherein a sock lining forms theinsole, which comprises securing the sock lining to the bottom of alast, then securing a shank on the last in overlapping relationship withthe sock lining, then applying an upper to the last andadhesivelysecuring its edge portions to the sock lining and the shank, thenskiving said edge portions, and then adhesively securing a sole to saidedge portions and shank.

5. The method of manufacturing a shoe which comprises securing upon alast a limp insole member and a stiff shank piece in overlappingposition, then applying an upper to the last and adhesively securing itsedge portions to the insole member and shank piece, beveling said edgeportions, and adhesively securing a sole to the edge portions and shankpiece.
